Pure water machines for research and experiments in the chemical industry are specifically designed to meet the needs for high-precision and high-purity water in chemical experiments. Their features are mainly reflected in aspects such as water quality purity, stability, adaptability, safety, and intelligence, as detailed below

1. Ultra-high water purity to meet stringent experimental requirements** - It can produce pure water of different purity levels, such as Type I water (resistivity ≥ 18.2 MΩ·cm@25℃) and Type II water. It can effectively remove impurities in water such as ions, organic substances, microorganisms, particles, colloids, and pyrogens, ensuring that experiments are not interfered by water quality (for example, avoiding the catalytic or inhibitory effect of ions on chemical reactions). - Some high-end models are equipped with ultra-purification columns and UV sterilization units to further reduce the total organic carbon (TOC) content (usually ≤ 10 ppb), meeting the needs of high-precision experiments such as trace analysis, chromatographic analysis (e.g., HPLC), and spectral analysis.

2. Stable operation with minimal water quality fluctuation - It adopts a multi-stage filtration system (pretreatment + reverse osmosis + ultra-purification) and high-precision control technology to ensure stable effluent water quality, avoiding the impact of water quality fluctuations on experimental repeatability (for example, in chemical synthesis reactions, water quality fluctuations may lead to differences in product purity). - Equipped with liquid level sensors and automatic start-stop functions, it automatically stops when the pure water tank reaches the set liquid level and starts automatically when there is a water shortage, maintaining stable water supply.

3. Adaptable to complex water sources and environments in chemical experiments - The powerful pretreatment system can handle raw water with high hardness, high salinity, and high organic contentthat may exist in chemical laboratories (such as industrial tap water or groundwater). It effectively removes large particulate impurities, residual chlorine, calcium and magnesium ions, etc., through pretreatment filters (such as PP cotton, activated carbon, and softening resins), protecting subsequent core components (such as reverse osmosis membranes). - The equipment is made of chemical corrosion-resistant materials. Components in contact with water are mostly made of materials such as 316L stainless steel, PTFE (polytetrafluoroethylene), and UPVC, avoiding equipment aging caused by residual chemicals in water or corrosive gases in the experimental environment.

4. Comprehensive safety protection functions - It has multiple safety protections, such as anti-dry burning of reverse osmosis membranes, overload protection of high-pressure pumps, water leakage detection and automatic shutdown, and alarm for excessive water tank level, reducing experimental interruptions or safety risks caused by equipment failures (for example, water leakage causing circuit faults or corrosion of experimental equipment). - Some models are designed with a real-time water quality monitoring system, which displays parameters such as resistivity and temperature in real time. When the water quality is substandard, it automatically alarms to remind users to replace consumables or perform maintenance.

5. Intelligent operation and convenient maintenance - Equipped with a touch screen control system, it can intuitively display operating status, water quality data, and consumable life. It supports one-key start and parameter setting (such as water production adjustment) with simple operation. - Consumables (such as filters and purification columns) are easy to replace. Some models are designed with a modular structure, allowing users to replace them quickly, reducing maintenance downtime. It also has a consumable life reminder function to avoid affecting water quality due to invalid consumables. 6. Water production efficiency and flexibility adapted to experimental scenarios - The water production capacity can be selected according to experimental needs (e.g., 0.5-100 L/h), meeting the water needs of small-scale experiments (such as beaker reactions) to medium and large-scale experiments (such as batch sample preparation). - It supports two modes: continuous water production and water storage in the tank. Some models can be connected to external water storage buckets to ensure a stable water supply even when the equipment is shut down.

7. Compliance with industry standards and certifications - Its design and performance generally comply with international or domestic standards such as ISO 3696 "Specifications and test methods for water for analytical laboratory use"and ASTM D1193, ensuring that the produced water quality meets the normative requirements of chemical research experiments. These features enable it to provide reliable high-purity water guarantee in scenarios such as acid-base reactions, solvent preparation, sample pretreatment, and instrumental analysis in chemical research, reducing experimental errors and improving the accuracy of research results.
